For today's Geo Quiz we visit one of Australia's top tourist attractions. Our destination today is a nice place to visit --- but you wouldn't want to stay long.

It was once a notorious penitentiary. In the 19th century, this prison was nicknamed "hell on earth".

The convicts were housed in a small town on Tasmania, Australia's southern most state. The name Tasmania by the way honors Abel Tasman. The Dutch explorer was the first European to spot the island.
